- Abstract
- Recently, a flexible loss recovery scheme, called Active Caching (AC) has been proposed to accomplish a Desired Communication Reliability (DCR) about the whole data packets at a source depending on the various applications. However, since AC does not consider the packet delivery rate of each wireless link on multi-hop forwarding paths, it increases the number of totally transmitted packets to achieve a DCR and thus grows the energy consumption of sensor nodes. Thus, this letter proposes a novel recovery scheme which can minimize the number of totally transmitted packets while satisfying a DCR. By geometric programming, the proposed scheme allocates an optimized one-hop packet transmission rate of each wireless link on the multi-hop forwarding path. © 2012 The Institute of Electronics, Information and Communication Engineers.
